friends. the news keeps coming. here's brian now with the news edge at 11:00. >> we're going to begin tonight with the suspected killer and serial rapist. where is that man? dc police are stepping up their efforts to find him. they say he's behind several sexual assaults and the deadly beating of a local woman 13 years ago in georgetown. now, investigators are using a tactic to help solve another high-profile crime, and for the first time, we're hearing from the murder victim's husband. fox 5's will thomas working this one now. >> reporter: brian, it was earlier this year we reported on the launch of the website to catch the east coast rapist. the site provided specific details on the attacks that had ties to our areas, the suspected east coast rapist was captured. and now dc police are taking a page from that effort to now catch a killer. a hot summer night, 1998, christine mrzai left a party in northwest and walked to her georgetown university dorm. that's when someone attacked

her, sexual assaulted her and beat her to death. the 28-year-old was newly married only a year and-a-half to a man named david hockos. he spoke to us by phone from his northern california home about the woman he loved and lost. >> it definitely never leaves me and i think it will affect me for the rest of my life. she was a very brilliant person, and it's a great loss. >> reporter: this is a composite sketch of the man who may be responsible. it was developed shortly after she was killed and the image was circulated. dc investigators were able to collect dna evidence from the scene and sent the profile to a national database. it linked her murder to eight unsolved sexual attacks in montgomery county between 1991 and 1998. >> he could be incarcerated on some type of offense where they don't take dna. he could be dead. he could be like everyone else and watch tv and movies and, you know, basically you'd have to

live under a rock not to understand a little bit about dna nowadays. >> reporter: in other words, the guy could still be committing sex crimes, but careful what he leaves behind. captain fair has been working homicides in the district for 20 years. he's now preparing to launch a website dedicated to generating lead snoos what we hope to do is combine the information between our murder and montgomery county's sexual assaults that we know are linked to the same suspect. they had a great idea with the east coast rapist is what i believe it's called, that website, i mean, there were cases all over and law enforcement were not opposed to borrowing someone's really good idea. >> i am very positive about this. i think it's a great idea so that people can understand what these crimes are, how they're connected. >> reporter: so the dna connects the same guy to sex assaults in montgomery county and the murder of mrzai. since that time, no new dna hits with the same man.

as you heard from the captain, they don't know if he's dead, alive, in jail or committing crimes in a different way. as to the man who was married to her, he told me tonight he finally remarried and has a 3-year-old child, brian. >> will thomas tonight. as to the charge of first-degree murder, verdict as to count 1, we the jury find the defendant not guilty. >> our other big story tonight, casey anthony acquitted of murdering her 2-year-old daughter, caylee. she was also cleared of aggravated manslaughter and aggravated child abuse. however, she was convicted on four misdemeanors. all of this unfolding in an orlando, florida courtroom. fox's debra boden has the story. >> reporter: casey anthony tearing up as the verdict is read, over and over again, it's not guilty. acquitting her of first-degree murder, aggravated manslaughter and aggravated child abuse. >> casey did not murder caylee.

it's that simple. you cannot convict someone until they've had their day in court. >> reporter: casey could have faced the death penalty if convicted of killing her 2-year-old daughter, caylee. instead, she celebrated with her defense team. the jury did find her guilty of lying to investigators, but with nearly three years in jail already served, she could walk free within days. >> i never ever criticize the jury. theirs is the task of deciding what to believe. >> reporter: he was acknowledging there was no hard evidence, no confession, no eyewitnesss. it was months before searchers finally found little caylee's body tossed in the woods near the anthony home. that delay hurt their case. >> especially a case like this, which is the proof, with no smoking gun, and a tiny victim who was reduced by the elements and skeletal remains, those

remains lacking in any chemical evidence that could be brought forward. this was a dry bones case. very, very difficult to prove. >> reporter: prosecutors say little caylee was suffocated with duct tape by her hard-partying mother who wanted to be free, while the defense said it was a tragic accidental drowning, but after nearly three years, we still don't know what really happened. >> while we're happy for casey, there are no winners in this case. caylee has passed on far, far too soon. >> casey anthony will be sentenced on thursday. meantime, the verdict is shocking end to the murder trial that spanned three years. the defense attorney had this to say about the controversial decision. >> you cannot decide this case on emotion. if you decide it on emotion, she's guilty, she's guilty. but if you decide it on the evidence, the evidence that's not there, then you must find

her not guilty. >> myfoxdc.com has complete coverage of the murder trial. you'll find the latest from florida, plus the entire reading of the verdict, and we want to know what you think about this controversial case, like myfoxdc.com on facebook and post your comments. the latest now on the corruption scandal in prince georges county. disgraced county council member leslie johnson is stepping down. today's announcement comes one week after she pleaded guilty to obstruction charges. she and her husband, former county exec jack johnson are awaiting charges on a council scandal. however, her resignation isn't effective until july 31. some say she should go now. >> the resignation should be as quickly as possible. >> as a resident of this county i think it would be nice if she would at least offer an apology. >> mrs. johnson stuffed nearly $80,000 in her bran and flushed a $100,000 check down the toilet

to hide the bribes her husband took from developers from the fbi. another arrested at the shooting near the caribbean festival. shawn is everywhere at 11:00. >> police arrested a second suspect in the murder of robert foster jr.. the 43-year-old was shot to death on june 25th just after the parade wrapped up. three others were wounded in the shooting. today, police arrested 23-year-old diante bryant, charged with murder. a professor will spend the next four years in prison. he was sentenced to possession of child porn. police arrested him last october after a university employee found the porn on the computer hard drive last october. a traffic nightmare on i66 because of this truck fire in fairfax. the tractor was loaded with bails of hay when it caught fire. five hours the highway was shut

>> breaking news. take a look at this, dramatic live pictures from the desert southwest tonight. kind of hard to see there, but this is a picture high above the city of phoenix partially engulfed in a gigantic dust cloud. it's desert sand blown by 60 miles per hour winds, becoming a thick mass of polluted air 50 miles wide in some places.

motorists are being told to pull over and wait to get out. no telling how long that thing will stick around. we'll continue to follow it live and, of course, on our website, myfoxdc.com. a disturbing trend in the medical world. critical medicine is in short supply, perhaps not even available at all, depending on what you're looking for. the problem many patients are facing right now and the number of drugs affected has nearly tripled. melanie alnwick has the money edge on that. >> reporter: pharmacy shelves across the country have more empty spaces these days, spaces that should be filled with important medications. jeff is the director of pharmacy medications for children's national medical center. >> if a child needs certain electrolytes in his iv and those are short, we're really scrambling. >> reporter: drugs for cancer treatments, infections, hard disease, diabetes, even adhd are

experiencing shortages. 211 last year, perhaps as many as 300 medications by the end of 2011. the american society of health and pharmacists is keeping track. >> just about every drug has been affected in the last year. a little less than half is related to production and in terms of keeping up with quality issues. >> reporter: there are other manufacturers to take up the slack if some go off line. some drugs are discontinued if they're not profitable to make. others get hung up in the regulatory process. usually alternatives are available, but doctors say it complicates how they treat their patients. >> that's definitely a major issue when they're admitting someone very ill. >> reporter: this doctor specializes in pediatric infectious diseases. >> it complicates things because we get a little bit out of our standard of care, and then we have to be a little bit more vigilant for unusual things we wouldn't usually be looking for. >> reporter: meanwhile in the pharmacy at the medical center, it means finding ways to reduce

waste. >> in most viles, there is overfill from the manufacturer. we're looking at different ways to repack it so there's no waste. >> reporter: and preserve every precious drop until supplies are plentiful again. one complaint doctors have is that they don't know there's a shortage until they've ordered the medication and can't get it. one thing they would like is to have the fda require manufacturers to give notice ahead of time so that people can prepare accordingly. it's also looking at trying to have the federal government do things like offer incentives like tax breaks to drug manufacturers so they'll continue to make those drugs that are no longer profitable. melanie alnwick, fox 5 news. coming up next, baseball legend roger clemmens in dc, his perjury trial kicks off tomorrow but his lawyers have scored a victory. a bizarre story in tonight's top 5, the possible link between flossing your teeth and getting

around 73 degrees, but again, it's cooling so slow tonight that we mainly make it down to 74 or 75 only. a spotty shower is possible tomorrow morning, not probable. we'll have kind of a mix of clouds and sun through the day tomorrow, high temperatures topping out in the upper 80s, so right around 90 degrees, and again, we have that chance of a shower or thunderstorm late in the afternoon. not only for tomorrow, but for thursday and friday. i said the week was looking good. sunny on saturday and sunday, temperatures in the upper 80s, and the way it's looking, some of the humidity getting pushed to the south, we'll be feeling a little bit dryer around here by the weekend. there's your forecast. stick around on the edge because dave feldman is coming back with the info on sports .
